How the Leetspeak (1337) works
Common letters are replaced by numbers or symbols that resemble them: a to 4, e to 3, i to 1, o to 0, s to 5, t to 7, and so on. Letters without a swap stay as they are.
Decoding reverses the number swaps back to letters. Because leet has many informal variants, this tool uses the most widely recognised substitutions.
Examples
History and origins
Leet grew out of 1980s bulletin board culture, where users replaced letters to slip past word filters and to mark themselves as insiders. Leet is short for elite.
It spread through early online gaming and hacker communities and now survives mostly as a nostalgic, playful style rather than a way to evade filters.
